Imagine exchanging recipes in the form of a piece of software instead of typed instructions on a website, and eating pizza with crickets on it instead of pepperoni.

This could be the future of long-term space travel, and even everyday life.

Anjan Contractor, who own Systems & Materials Research Corporation, has created a universal food synthesizer that uses a 3D printer to make food -- and he just received a six-month, $125,000 grant from NASA to create a prototype.

His prototype 3D food printer is based on a piece of open-source hardware called the second-generation RepRap 3D printer.

The universal food synthesizer would read recipes in software form, where instructions on how to make certain foods would be embedded. This software tells the 3D printer which powders to mix with which liquids.

The software will also be entirely open-source, so that others can look at the code and create recipes.

After the 3D printer "reads" the recipe, it uses a combination of powdered and certain liquid ingredients to make food layer-by-layer -- just like other 3D printed materials. Powdered forms of ingredients are used because they last longer.

“Long distance space travel requires 15-plus years of shelf life,” said Contractor. “The way we are working on it is, all the carbs, proteins and macro and micro nutrients are in powder form. We take moisture out, and in that form it will last maybe 30 years.”

Users of the universal food synthesizer can add the exact amount of proteins, carbs, etc. that they want for nutritional value.

The first idea for the prototype is a pizza, where the printer would make a dough layer first, then a tomato paste layer and finally, a protein layer made of insects, plants or milk-based powder.

While this 3D printed food is mainly for long-term space travel right now, Contractor believes it could also have a place in every kitchen as the human population increases. Toward the end of the century when the population is expected to be around 12 billion, a universal food synthesizer could eliminate food waste and ensure that all 12 billion mouths are fed with balanced nutrition.

Glop....Artificially colored and flavored glop. Other than the "in space for a long time" application it will never replace real food. If people would wake up from the fast food mentality, you would be surprised at what you find. There is no substitute for good quality real food.

Glop- research Hydrogenated Vegetable Oil and see what they make of it. It might make you sick on what it is and how they process it. You'd be surprised to see what it's in that you eat. It's still being widely used in everything. Even with all the exposure nothing has changed.
